cnmn'n onwrrna ron wmnsnrnnns am) vrma Lr'xn for Windshields' and; the like, of which thefollowing is a full, clear, concise, and exact description, reference being had to the ac- .companying drawings, forming a part of this specification. A My invention relates to cleaners or wipers for wind shields and the like.

One of the objects of the invention is to provide a sim le, practical and effective form of wind 'eld cleaner.

Another object of the invention is to ar-` ran ve for the ready attachment ofthe wiper` or c eaner to the wind shield and the ready detachment of the same therefrom.

- Another object of the invention is to provide a wind shield wiper which can be used o'n all pes of lwind shields.

Anot er object of the `'nvention is to .arrange for a tight and effective attachment of the .wiper to the .wind shield and to secure adjustment so that the attachment may be made as tight and secure as desired.

Another ob]ect of the invention is to lsecure a uniform pressure of the wiping member to the wind shield glass or other surface to be cleaned. 'f

Anotherv object of the invention is to arrange to apply'the pressure of the wiping member to the glass without-requiring undue pressure on the handle or other part of the device. Another object of the' invention is to secure flexibility in the material forming the wipinglmember. l

In t e accompanying drawings Fig. 1 1s a open automobile and a wiper embodying my present invention applied thereto;

view showing part of a wind shield of an Fig. 2 is an end elevation of the principall portion of the wiping device and said wind shield;

3` and 4 are rossisections taken respectlvely o'n lines 3;-3 and 4-4 in Fig. 1;`

Fig. 5 is a viewshowing the device applied to a closed car. l l

Referring to the draw I show a wind shield havin va glass 1 an a rim 2 extending along `t e upper edge of the glass 1.

Mounted Qn this wind shield is a wiper A embodying my present invention.

Application mea mgm 1, i921. semi no. 483,798.

This wiper A has a handle 3 to be grasped by the hand. of the operator or person driv-` 1n the automobileand a wiper arm 4 on the s1 e of the wind shield opposite to the handle 3. A cross member 5 extends .between the handle 3 and arm 4, said member 5 being preferably made as or-support 4.

For securing the member 5 to the han- A dle 3, show the latter provided at its upper end wlth an elongated bearing or sleeve 6 adapted to enclose the end portion of the member 5. The member 5 may move in the i A bearing`6 but it is normally clamped firmly there1n,as' w1ll appear from the construction hereinafter described. Said member 5 may be removed from bearing`6 when desired to remove the device from the wind shleld or for other purposes. This bearing 6 has a downwardly extending socket portion 7 which receives the end 8 of the handle 3, said end-8 being secured in said socket 7, as by weldlng. A ring 9 is fitted over the socket 7, having a sliding connection therewith, and a nut 10 isv arranged onthe threaded end 8, whereby by screwing the nut upwardly the ring 9 will be forced and clamped against the e member 5, it eing understood that the sleeve 6 has its lower side made open, as shown in Fig. 4. Thusthe handle 3 mayl be 'ezgil attached to the cross member 5 and e the same, and may be as readilyv detached from the same.

The cross member 5 is mounted so that it may be turned as the handle 3 is swung to one side or the other when operating the device. Tov such end I- show two clamping vmembers 11 and 12 mounted on opposite sides of the wind shield. The member 11 has an upper -straight portion 13 which lies alongside the wind shield rim 2 and also has an angular -portion 14 which extends along the under side of said rim and also has a substantially vertical flat portion 15 adaptsurface ofthe glass 1. The clamping member 11 also has a horizontal portion 16 at its upper end extending 'crosswise of the portion'13 and preferably substantially at right angles thereto. The clamping member 12 'has a horizontalportion 17 arranged abovethe horizontal portion 16 of the member- 11 and arranged to lie immediately above and in contact with the same. The ends of this part of the wiper arm i osed under surfacer of the l mly in position in connection with ed to fit against and contact with the upper* portion 17 are turned down as at 18 so that they come down along the end edges of the portion 16 and'grasp or hold said portion between them and thereby hold the clamping \members against longitudinal movement.

The member 12 also has a Vertical portion 19 and an angular portion 20, the latter adapted to come into position opposite the other under side of the wind shield rim 2. An adjusting screw 21 passes through the portion 20 and comes in contact with the rim 2.

A pair of screw bolts 22-22 pass through the clamping members 11 and 12, the heads 23 of said boltsengaging the outer side of the portion 13 of the clamping member 11 and nuts 24 on said bolts 22-22 engaging the outer side of the vertical portion 19 of the clamping member 12. The horizontal connecting member 5 passes through the clamping members 11 and 12 between the bolts 22-22, as shown' in Fig. 2. B adjusting the nuts 24 on the bolts 22 the c amping members 11 and 12 may be brought together and clamped upon the wind shield rim, and-by adjusting the screw 21 pressure may be applied to the rim 2 to supplement this clamping action and so hold the cleaning device as a whole firmly and securely upon the wind shield.

At the lower end of the wiper arm 4 a wiper member 27 is mounted. This member 27 is preferably in the form of a metallic holder having two thicknesses 28-28 of flexible rubber material secured to it and between its opposite sides, as best seen in Fig. 3. By having two thicknesses 28 both comparatively thin, the wiping material is more flexible and a better cleaning action is secured.

The mounting between the wiper member 27 and the wiper arm 4 is preferably such as to permit uniform pressure throughout the entire length of the member 27 and also to permit a certain amount of rolling or flapping action on the part of the wiper member so as to secure effective cleaning.

Tn the arrangement shown the wiper member 27 is supported' by a spring member 30 preferably in the form of a bow-shaped or arched metallic member. The wiper member 27 is secured as .-by a pivot 31 to the lower end'of the member 30, whereas the upperend 32 of the member 30 is flanged so as to grip or engage the member 27 on opposite sides, there being a sliding joint between the member 27 and end 32. The member 30 has a channel shaped central shown in Fig. 3, in which t e lower end of the arm 4 is fitted, said end 4 being curved as a 34 and provided withl a cross pin 35 to hold said end 34 in position. The end 34 is loose enough in the part 33, however, to permit a certain amount of rolling or flapping action of the member 30 with reference to ortion 33, best atraso@ the arm 34. Thus the joint ory connection between arm 4 and'wiper member 27 through the medium of arch-shaped spring 30, per mits pressure lto be applied to the wiper at separated points, as for example nearly at the opposite ends of the same, as shown. This distributes the pressure, evenly along the entire length of the wiping member which would not be the case if said member were supported and acted upon only at its middle or central point. Adjustment of the pressure is permitted by a sliding connection between end32 and member 27. Furthermore, the duplex wiping members 28 and the rolling action of Nmember 30 with reference to arm 34 allow a Very eective cleaning action. The channel portion 33 preferably has its outer side closed, as by yadditional apertures 30a for pin 31, to permit mounting member 27 in di'erent vertical adjustments.

Thus it will be seen that the device may be firmly' secured upon the upper edge or rim of the wind shield and also that/sufficient pressure may be obtained to apply suflicient pressure to the cleaning member 27 to insure efl'ective'cleaning action. Also that since handle 3 is adjustable on connection 52 further pressure may be secured if desired by adjusting said handle toward arm 4, with result that wiper 28 will be pressed closer on wind shield glass.

Tn Fig. 5 the device is shown applied to a closed car, in which case the clamping members 11 and 12 are omitted and the connecting member 5 passes directly through the wind shield rim 2. A washer 38 is preferably provided on the side of the rim 2 next to the handle 3.

Tt will be understood that changes and modificationsv may be made without departin from the spirit of the invention.
